When a project is started, a new structure Building Site will be created in the target region (the structure will resemble a construction site). When the structure is completed it will be replaced by the finished structure.
There are no restrictions on player citizenship, every player can participate and help building the structure.

By clicking this link, and if the needed materials are in the inventory, the players can collaborate to build the structure for some hours and contribute to reach the working hours target. As soon the project building starts, all the materials will be removed from the inventory. When the target hours are reached, the structure will be ready.

It will be possible to work for free for a maximum of 9 hours. Some slots for paid work of 3, 6 or 9 hours will be available if there is enough coins available in the structure.
